This invention relates to an automobile lock ofthe type in which a bolt is permitted to; enteran operative unit of the automobile and V N prevent the same from being manipulated;

In my invention, Ihave applied my lockto the gear shift mechanism, but it should be understood that it-ispossible to apply the same to any other desired unit-of the vehicle.

My lock is of the coincidental type in'which the locking mechanism operates in conjunction with a switch mechanism, so that whenever the ignition circuitis opened, the look-- ing mechanism will become operative.

It is sometimes desirable, whenthe car is in 3 motion to turn off the ignition to permit the car to coastand at the sametime leave the mechanism unlocked. In prior looks, it has been possible to turn oil the ignition manually without use of the key, when the lock has once been opened. By such an arrangement the co-incidental feature of the look was detion is of the usual type and slnce it forms no 1y operated at alltimes. In my lock, manu al operation of the switch, is never possible except to absolutely lock theignition' and operating mechanism at one and the same time. In other words; 'Imake it impossible to open the ignition circuit manually, with-1 out, at the same time locking some operative part ofthe car. I

lhe invention is more fully described in the specification and in the drawing, wherein Fig.

1 is a section of my gearshift locking mechanism and the cylinder lock for operating the same, part of this figure being taken on the, 7 line 11 of Fig. 2.. Fig. 2 isa partial section! of Fig. 1 0n the line 22. Fig; 3 is a view of the switch mechanism showing the circuit in open p osition. Fig. is a similar view sho-w:

ing the circuit in closed position. Figs. 5 t

and 5A are sections of Fig.1, taken at point 5-5, showing the position of the cylinder its lower end by a screw 4, a 'still lower por- 515 tion 5 which acts as a bearing for the locking, bolt 6. As shown in Figure 1, this'bolt 6 r is adapted to be thrown into a plate7 where-- by this plate will hold the gear shift lever from movement. A ball 8 is mounted on the d lever 1 in any manner desirable and this ball acts as a bearing for the gear shift lever, as.

is usual in constructions of this type... This ball is slotted at 9 and a screw 10 fits into the I same to limit the direction of movement of the ball in a rotary direction. This construc-,

part of my invention, it need not beifurther described. I

The bolt is constructed for convenience in '16 two parts, the lower portion 6 being fastened by means-of screw 11 to the .upper portion 12.

This construction is devised in order to simrod 16' is in turn connected to the plug 17 of the cylinder 17 tion 18. p v e r My cylinder locking mechanism is of unmeans' of the pin connecf usual construction. It may be of either the sliding tumbler type orthe pin tumblertype, since its internal lockingconstruction isunimportant. A; pin-19 shown in section in Fig. 1 is adapted to extend from aiportion of i "theball sleeve 2 into a slot 20 ofthe cylinder,

"7 and permit future operation of the gear V member.32. This contact member 32- isin.

so as to limit the vertical movement of the same and prevent its rotational movement.

As was previously described the rod 16 is fixed at the point 18 to the plug of the cylinder and has no connection with the cylinder shell itself. Thus, while the cylinder cannot rotate, the plug may rotate and move with it the rod 16 and the bolt mechanism 12 and 6. A pin 21 which extends from the ball sleeve 2 fits in a cut-away portion 22 of the plug and limits the movement of the same, both in a rotary and longitudinal direction. 7 The. pluglT of the cylinder 17 is equipped with looking bolts 261which are more fully shown in Figs. 5 and 5A; While these bolts" normally lie partially within the plug, (Fig;

5) they are not under the control ofthe'plug in the usual manner. plug isrotated, these bolts will be acted on bythe cam, surfaces 27 ofthe grooves' 28 to retract the same within the plug. This action is fully shown in Figures5 and 5A, illustrating respectively and unlocking position.

The gear shift rod 1 is hollow and is equipped at its inner surface with a shoulder 23, this shoulder 23-beingthe support for a ring 24 which in turn supports a spring 25.

This spring 25'lying' as itdoes, between thering24 and a shoulder 14 of the universal cap 14' tends to move the locking. bar mechathe bolts in locking H ever, when the:

. tacts 37, and 34 is therefore open. The cylindQ lock, is alsoin its lowerlocking position with bolts26 fittin'g 'within the lockingv groove 28 "of the ball sleeve 2.

,Figs. 3and 4'illustrate the position of the contacts when thethe circuit is in open and closed position respectively. As was previously explained, key operation of the cylinder17 will'cause the entire locking bolt assembly'tomove to a level above that-illusby the pin and slot connection 21' -22 of plug 17-. --This rotation has brought thef-down nism in an upward and unlocking direction;

It will now be quiteobvious that when the plug 17 Y is rotated so as to cam its bolts 26 out of the locking groove 28.;that the spring 25 will then be free to push the entire locking trated' 'in Fig. 1 so as to withdraw the bolt 6 from the plate 7. s 1

' This riseto upper level is suflicient to carry the contact ring 32 into 'the plane of the con-- tacts 34 'of-"the ignition circuit. However,

to allow this rise to an upper level, the locking rod'and cylinder assembly wereof necessity rotated a 'limitedamount as determined ward portion 33 of insulating ring 30 oppo:
